It depends on what you like. I had to choose between electrical engineering, math, and physics. I was under the impression that electrical engineering was the most immediately employable one, and that it still has a sufficient amount of math and physics in it. Fortunately, it turns out I enjoy some fields of electrical engineering quite a bit (though others, not so much), so I plan on going into those fields.

I couldn't, so I did both. I would say unless you're planning on physics as a career, the best types of jobs (in terms of stress, income, etc) you could get with a physics bachelor's would be the same ones you would get much more easily with a CS degree. But if you really can't decide, you could always look into a double major...
